NOTE 13 – STOCK COMPENSATION PLANS

Employees' Plans

On March 12, 2012, the Compensation and Organization Committee ("Committee") of the Board of Directors approved a grant under our shareholder-approved ICE Plan for the performance period 2012-2014. A total ofÌý426,610 shares were granted under the award, consisting ofÌý312,540 performance shares andÌý114,070 restricted share units.

For the outstanding ICE Plan award agreements, each performance share, if earned, entitles the holder to receive a number of common shares within the range between a threshold and maximum number of our common shares, with the actual number of common shares earned dependent upon whether the Company achieves certain objectives and performance goals as established by the Committee. The performance share grants vest over a period of three years and are intended to be paid out in common shares. Performance for the 2010 to 2012 performance period and 2011 to 2013 performance period is measured on the basis of two factors: 1) relative TSR for the period, as measured against a predetermined peer group of mining and metals companies, and 2) three-year cumulative free cash flow. Performance for the 2012 to 2014 performance period is measured on the basis of relative TSR for the period, as measured against a predetermined peer group of mining and metals companies. The final payout for the 2010 to 2012 performance period will vary fromÌýzero toÌý150 percent. The final payouts for the 2011 to 2013 performance period and the 2012 to 2014 performance period will vary fromÌýzero toÌý200 percent of the original grant. The restricted share units are subject to continued employment, are retention based, will vest at the end of the respective performance period for the performance shares, and are payable in common shares at a time determined by the Committee at its discretion.

Upon the occurrence of a change in control, all performance shares, restricted share units, restricted stock and retention units granted to a participant will vest and become nonforfeitable and will be paid out in cash.

Our Board of Directors approved the new 2012 Equity Plan on March 13, 2012, and recommended it to our shareholders to approve at the 2012 Annual Meeting of Shareholders. If approved, the 2012 Equity Plan will be effective as of March 13, 2012.

Determination of Fair Value

The fair value of each grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. A correlation matrix of historic and projected stock prices was developed for both the Company and our predetermined peer group of mining and metals companies. The fair value assumes that performance goals will be achieved.

The expected term of the grant represents the time from the grant date to the end of the service period for each of the three plan year agreements. We estimated the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds, with a term commensurate with the remaining life of the performance plans.

The following assumptions were utilized to estimate the fair value for the first quarter 2012 performance share grants:

The fair value of the restricted share units is determined based on the closing price of the Company's common shares on the grant date. The restricted share units granted under the ICE Plan vest over a period of three years.
